BRAKE.

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed March 3, 1906. Serial No. 304,009.

To all whom it may concern:

Be it known that I, HENRY C. NEALE, a citizen of the United States,residing at Phil adelphia, in the county of Neshoba and State ofMississippi, have invented new and useful Improvements in Brakes, ofwhich the following is a specification.

This invention relates to brakes for wagons and vehicles generally, theobject of the invention being to provide a brake especially designed forWagons and adapted to be mounted wholly upon therunninggearwithout anyconnection whatever with the wagonbody, a further object of theinvention being to construct the parts'of the brake mechanism in suchmanner that such mechanism will not interfere in any way with loadingand unloading the wagon, the said brake mechanism as a whole beingcarried by the truck or running-gear and located out of the way.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully illustrated, described, and claimed.

In the accompanying drawings, Figure 1 is a bottom plan view of therunning-gear of a wagon, showing the improved-brake mechanismapplied'thereto. Fig. 2 is a vertical longitudinal section through thesame. Fig. 3 is an enlarged detail perspective view of the bracketconnected with the rear axle. Fig. 4 is a detail view of the forward endof the slide-rod, showing the provision for securing the brake actuatingcable thereto. Fig. 5 is a sectional elevation on the line mm of Fig. 6,showlng the gearing by means of which the brake connections are throwninto operation. Fig. 6 is a cross-section through the same. Fig. 7 is afagmentary perspective view of one end of the sliding rack, showing thear rangement of teeth thereon. Fig. 8 is a detail view of the ferrule orslip-collar used with the sectional hand-lever.

The brake mechanism contemplated herein comprises, essentially, abrake-beam 1, extending beneath the reach-bar or couplingole of thewagon and suspended. by means of links 2, which are supported at theirupper ends by a cross-bar 3, extending across the coupling-pole orreach-b ar, as shown in Fig. 2.

The brake-shoes (shown at 4') operate in connection with the rear wheels5, and the brake-beam is moved toward and away from the wheels 5 bymeans of a brake-rod 6, the

rear end of which is pivotally connected at 7 to one arm 8 of atwo-armed lever having its journal portion 9 mounted in a bearingbracket10, connected with the rear axle 11. The other arm 12 of said two-armedlever is connected, by means of a pivotal link 13, to the rear end. of aslide-rod 1 4, which is mounted in one or more guides 1 5 ,connectedtothe coupling-pole or reach-bar 16, as shown in Fig. 2.

17 designates a relief-spring which extends upward from and is connectedfast to the bracket 10 and. provided at its free end Wit-I1 an eye 18,through which the arm 12 of the two-armed lever passes, said springexerting its tension to draw back on the lever-arm 12 and rock the arm 8upward to allow the brake-rod 6 to recede and permit the brakeshoes 4 tomove out of contact with the wheels. The relief-spring 17 also acts onthe remainder of the brake mechanism to restore all of the parts totheir normal inoperative position in a manner which will hereinaftermore clearly appear.

The forward end of the rod 14 is provided with an eye 19, and at oneside thereof there is arranged a hook20. 21 designates theoperating-cable of the brake connections, which has its rear endinserted through the eye 19 of the rod 14 and wrapped several timesaround itself, as shown at 22, the extremity of the cable being finallyslipped under and engaged with the hook 20 in the manner illustrated inFig. 1. The forward end of said cable 21 is connected to a drum orpulley 23 and is adapted to be wound thereon for drawing the rod 14forward and applying the brakes in the manner above described. The drumor pulley 23 is fast on a winding-shaft 24, extending parallel with thefront axle 25 and having fast on its outer end a winding gear-wheel 26.The inner end of the shaft 24 has bearing in a bracket 27, connectedwith the front axle, while the outer end of said shaft has bearing in apair of parallel housing-plates 28, secured to the bolster of the frontaxle and extending above the same. The plates 28 are provided upon theirinner sides with grooves in which is mounted a sliding rack 29, providedon its under side with teeth 30, which engage the teeth of thegear-wheel 26 and turn said gear when the sliding rack is movedlengthwise. Motion is imparted to the sliding rack 29 by means of arack-actuating gear 30 which meshes with teeth 31 on the upper face ofthe rack, as shown in Fig. 5. This gear-wheel 30 is IIO mounted fast ona short shaft 32, mounted in bearings on the plates 28, and secured faston the outer end of said shaft 32 is a pinion 33, which meshes withanother pinion 34, said pinions being held constantly in mesh with eachother by means of a pinionframe comprising oppositely-arranged side.bars or plates 35. By reference to Fig. 2 it will be seen that theframe 35 is capable of being moved upward and downward around the shaft32 as a center for the purpose of moving the pinion 34 into and out ofengagement with a gear-wheel 36, fast on the hub of the adjacent frontwheel 37 The pinion-frame 35 is vibrated or moved up and down by meansof a hand-lever 38, fulcrumed at its lower end by means of a stub-shaft39, mounted in a suitable bearing 40, extending upward from one of theside plates 28. The hand-lever 38 is provided with a laterally-extendingarm 41, to which are attached one or more pivotal links 42, whichconnect pivotally with the vibratory pinion-frame 35.

It will now be seen that as the hand-lever 38 is rocked on its fulcrumthe pinion-frame 35 is raised or lowered, thereby moving the pin ion 34into or out of mesh with the wheel 36, and as the wagon-wheel 37revolves motion is thus transmitted, through the, gears 36, 34,

33, and 30 to the sliding rack 29, the latter imparting rotary motion tothe gear-wheel 26 and the shaft 24 and pulley or drum 23, therebywlnding up or unwinding the cable 21 for operating the brakeconnections.

Mounted between the plates 28, just over the sliding rack 29, is adetent 43, the same being pivoted intermediate its ends at 44 and havingthe engaging point thereof pressed downward by means of a spring 45,said detent engaging ratchet-teeth 46 on the upper side of the slidingrack 29 to hold said rack after the same has been slid forward in theoperation hereinabove described, the detent holding the rack in suchposition until released by the hand-lever.

Connected to the heel end of the detent 43 is a spring 47, which extendsupward and bears against a flat face 48 on the stub-shaft 39, to whichthe lower end of the hand-lever 38 is fastened, the function of thisspring being to hold the hand-lever in an upright position when thebrake mechanism is inoperative or not in use. The hand-lever 38 isprovided with a lug 49, which in the return movement of said hand-leveracts against the heel end of the detent 43, depressing the said heel endand correspondingly elevating the point of the detent, so as to throwthe same out of engagement with the teeth 46 of the rack, therebypermitting the rack to slide back and resume its normal inoperativeposition, the rack being drawn back by the relief-spring 17 and theconnections between said spring and the sliding rack 29.

The upper portion or section 50 of the the lower section 38 of saidhand-lever, so that when the broke is not in use the upper longersection of the lever may be swung downward out of the way. The twosections of the lever are held in longitudinal alinement with each otherby means of a ferrule or slip-collar 52, which embraces the overlappingportions 'of the two lever-sections and is adapted to be secured infixed relation to said over lapping portions by means of a bindingscrew53.

In operation to apply the brake the handthat the pinion 34 is moveddownward into engagement with the revolving wheel 36, carried by thefront wheel 37. This imparts motion to the train of gears and slides the26 and the shaft 24 and winding the cable 21 on the pulley or drum 23.This draws forward on the slide-rod 14, rocking the twoarmed lever journaled in the bracket on the rear axle and pulls the brake-rod 6, soas to move the brake-shoes 4 into engagement with the rear wheels 5. Theparts are held in this position by means of the detent 43. To releasethe brake, the hand-lever 50' is moved forward, which has the effect ofrock ing the detent 43 out of engagement with the rack 29, whereupon therelief-spring 17 restores all of the parts to their inoperativeposition.

I claim 1. A brake comprising a brake-shoe, brake connections thereforembodying a cable, a winding-shaft for said cable, a winding-gear onsaid shaft, a reciprocatory rack meshing with said winding-gear, a gearon one of the vehicle-wheels, means adapting said lastnamed gear toactuate the rack, and a handlever controlling the actuating connectionsbetween the gear on the vehicle-wheel and said rack.
